Trillium hibbersonii
Also called Dwarf Trillium, Dwarf Western Trillium
Hibberson's trillium is a small, rhizomatous woodland perennial native to western Vancouver Island, long thought to be a dwarf form of Trillium ovatum. Grow it in cool, moist, shaded woodland conditions, and note it is rare with only four known populations.
Trillium hibbersonii is a species of flowering plant in the bunchflower family Melanthiaceae. The specific epithet hibbersonii honors the English Canadian surveyor John Arthur Hibberson (1881–1955) who first collected this plant in 1938 on Vancouver Island in British Columbia. Hibberson and his son propagated the trilliums, selling them to buyers in England and other European countries. In 1968, Leonard Wiley coined the Latin name Trillium hibbersonii, a name that has since been used by horticulturists without reservation.
When botanists finally became aware of Hibberson's trillium in 1974, it was circumscribed as a dwarf form of Trillium ovatum that occurs occasionally throughout the range of the species (which spans some nine states and provinces in western North America). Apart from Vancouver Island, no such trillium has ever been found.
Trillium hibbersonii is found on the west coast of Vancouver Island in British Columbia. As originally described, it was thought to occur occasionally throughout the range of the species, but that is no longer believed to be true. There are just four known populations of T. hibbersonii, all on Vancouver Island, which makes the species a source of conservation concern.
